Kenneth Rust is a key player in redeveloping an old post office in downtown Portland, Ore. Denise Olson is pushing new technology to save Phoenix money on procurement. Jim Beard figured out how to update and expand Atlanta’s water and sewer systems while avoiding a scheduled rate hike.

These tasks require different kinds of know-how, but Rust, Olson and Beard all have the same job title: chief financial officer. It’s a position that has morphed in recent decades. Where CFOs were once primarily in charge of numbers -- making sure the books were balanced, bills paid and audits clean -- they now are called on to be strategists with an eye to developing the city’s economy. And where CFOs came to the job touting experience in a local or state finance department (and perhaps a stint as city controller as well), they now hail from more varied backgrounds. Just as in the private sector, many public enterprises are looking for CFOs with talents that include creative thinking, communication skills and long-range planning -- and for good reason. Today, just about everything a municipality does is either under the CFO’s purview or at least under his or her watchful eye. “Almost every major decision the city makes,” Beard says, “I get to be in the room.”
